Hi, Pardon me if I'm misunderstanding, but it very much seems to me that the gdm/lightdm configuration scripts are unconditionally setting the default value of the debconf choice to gdm, irrespective of the previous value of the setting.
Is that normal behaviour ? In the transcript below I would have found more logical to see a GET just after the two METAGET's.
